Abstract
This work explores the wave dispersion behavior of functionally graded graphene platelet (GPL) reinforced polymer composite plates with the piezoelectric layers mounted at the surfaces. The weight fractions of GPL distribute symmetrically in the multilayered structure with three patterns. Considering the closed-circuit electrical condition, the electric potential obeys a cosine variation along the thickness of piezoelectric layer. The kinematic relations of the piezoelectric composite plate are characterized using the Reissner-Mindlin theory along with the Hamilton's principle. The supplementary governing equation for the electric potential component is obtained through the Maxwell's equation. The analytical dispersion relations are described by a quadratic eigenvalue problem in terms of wavenumber and frequency. The influences of GPL distribution pattern, GPL weight fraction, GPL size, and piezoelectric layer thickness on the wave dispersion responses are studied in detail. The results manifest that the presence of piezoelectric layer greatly reduces the wave propagation velocity and cut-off frequency. Furthermore, this investigation provides a guideline for the design and development of smart graphene reinforced polymer composites.
期刊介绍:
Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses.
Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering.
The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
